MECHANICAL APPARATUS.

Application filed February 27, 1922. Serial No. 539,564.

This invention relates to mechanical apparatus, and with regard to certain more specific features, to measuring and nonmeasuring pumps for liquids.

Among the several objects of the invention may be noted the provision of a simple and inexpensive device for preventing unauthorized withdrawal of liquid by means of a pump; and the provision of compact and durable means for looking a storage tank. Other objects will be in part obvious and in part pointed out hereinafter.

The invention accordingly comprises the features of construction, combinations of elements, and arrangements of parts, which are exemplified in the construction hereinafter described and a scope of the application of which will be indicated in the following claims.

In'the accompanying drawings, in which is shown one of various possible embodiments of this invention,

Fig. 1 is a front elevation,

Fig. 2 is a fragmentary left side elevation;

Fig. 3 is a vertical section on the line 3-3 of Fig. 1, on an enlarged scale; and

Fig. 4 is a view similar to Fig. 3 but showing the parts in unlocking position; for c0nvenience of comparison with Fig. 3, the de vice is shown in Fig. 4 with the pipe vertical, whereas in practice it normally occupies a position inclined to the vertical when in unlocking position.

Similar reference characters indicate corresponding parts throughout the several views of the drawings.

Referring now more specifically to Fig. 1 of the accompanying drawings, there is illustrated a tank 1 for the storage of oil or other liquid. 'Mounted upon and extending into the tank 1 is a pump 3, here shown illustratively as adapted for operation by means of the hand crank 5.

The lock 7 for locking the pump, quantity handle 9 for determining the quantity of liquid to be delivered, and the meter or total-izer 11, are shown somewhat conventionally as they form no feature per se of the present invention.

During normal operation of the pump the liquid is discharged through the nozzle or other terminal 13.

Liquid is supplied to the tank through the supply aperture 15 in the top of the tank. At this time the cover 17 is swung up about its hinge 19. i i

Extending upwardly (Fig; 1) from the cover is a drip pipe or tube 21 having threaded to. it at its upper end a lower joint member 23, upon which is pivotally mounted an upper joint member 25. The latter memberwhen in locked position 1, 2 and 3) extends up into the apron or hood 27 or the terminal or nozzle 13. In this locked position, operation of the pump serves to discharge liquid through the nozzle, but the liquid merely passes down through the upperand lower joint members 25, 23 and pipe 21 back into the tank, and none of the liquid can be obtained by the operator. The parts may be retained in locked position by suit- 1 ablemeans such as a padlock 29 (Fig. v1), serving to lock together the upper and lower omt members and to prevent relativemovement of said members. The: arrangement of parts is such that the pipe and joint members cannot be swung as a whole about the cover hinge 19 as an axis because the hood 27 prevents movement of the upper joint member when the joint members are locked together. i

When the device is to be unlocked, padlock 29 is first removed. Then the pipe is swung about the cover hinge as an axis, that is, rearwardly in Fig. 1 (counter-clockwise in Figs. 2- and 3). During such movement the upper joint memberfswings clockthe i wise (Figs. 2 and 3) withrespect to thepipe and lower joint member, thereby bringing the upper end of the upper joint member down a little closer to the tank and permitting said upper end to pass out beneath the hood 27. The movement of the pipe counterclockwise (Figs. 2 and 3) is preferably continued until the pipe rests in horizontal position, or at least near enough to the hori- The lower portion 35 of the outer wall of the upper member 25 is approximately coaxial with the pivot 37 between upper and lower members, and is nearer to the pivot than is the adjacent upper portion 33' of the outer wallfof the lower member 23. Since.

' in normaloperation during unlocking the lower member swings counter-clockwise (Fig. 3) and the upper member swings clockwise (Fig. 3) with respect to the lower member, any liquid that may be dripping from the upper member drips down into the locked together. of the pivots and nozzle 1S shown in the accompanying drawings, wherein these three for said aperture, a pump adapted to dis charge liquid vfromsaid receptacle, a nozzle on said pump through which said liquid is discharged, the nozzle being located at a liquid from the apparatus either throu h i the aperture 15 in the tank or by operation pipe into coaxial relation with the cover 17.

The device effectively prevents theft of of the pump, and since the cover 17 cannot be raised when the device is lockerhthesingle padlock 29 serves to protect against theft by way of the pump, thereby avoiding the necessity of havingany lock on the cover 17 or pump.

. The pivots 19 and 37 for cover and joint members respectively are so located with respect to the hood 27 of the nozzle as to prevent opening of the cover when the joint members are locked together and so as to permit opening of the cover as above described when the joint members are not A preferred arrangement points are approximately in the same stra1ght line, as indicated in F1g. 2.

The pump may be of the measuring or non-measuring type.

From the above it will be seen that the several objects of the invention are realized, and other advantageous results attained.

As various possible embodiments might be made of the above invention and various changes might be made in the embodiment above set forth it is to be understood that "allmatter herein set forth or shown in the accompanying drawings is to be interpreted as illustrative and'not in a limiting sense. I claim: V p 1. In apparatus of the class described, in
